3 Description

The DRV134 and DRV135 are differential output

amplifiers that convert a single-ended input to a balanced output pair. These balanced audio drivers

consist of high performance op amps with on-chip

precision resistors. They are fully specified for high

performance audio applications and have excellent ac specifications, including low distortion (0.0005% at 1

kHz) and high slew rate (15 V/μs).

The on-chip resistors are laser-trimmed for accurate

gain and optimum output common-mode rejection.

Wide output voltage swing and high output drive

capability allow use in a wide variety of demanding

applications. They easily drive the large capacitive loads associated with long audio cables. Used in

combination with the INA134 or INA137 differential receivers, they offer a complete solution for

transmitting analog audio signals without degradation.

The DRV134 is available in 8-pin DIP and SOL-16

surface-mount packages. The DRV135 comes in a

space-saving SO-8 surface-mount package. Both are specified for operation over the extended industrial

temperature range, –40°C to +85°C and operate from

–55°C to +125°C.
